I have 4 things in particular I'd like to see implemented:
First, Give Dark Knight 2 or 3 lvls of the Elemental Celerity job trait. The devs themselves have said they would like to see drks using more magic. The best and easiest way to accomplish this would be to allow drks to cast their elemental spells faster. It would not be overpowered, simply because drks only get tier 3 of the elemental nukes anyway. What's the harm in letting them cast those nukes faster? It would give Occult Acumen more of a use besides drain and bio.
Second, I would like to see a point system implemented in Walk of Echoes. Kinda like the old Einherjar. Give participants a certain number of points based on the difficulty of the conflux. Set up an npc (perhaps kupofried himself) to allow players to spend those points on items like the WOE weapon coins, devious dice, and liminal residue. Remove the random drops completely, and let players earn their own rewards. balance the cost versus the average amount of time a full empy weapon from abyssea drops would take to get. make the dice and residue ex, so players couldn't sell them and do more damage to the already inflating in-game economy.
The gear drops from WoE could remain as is, or set them up to be bought with points and rare/ex as well. Set up temp item chests so players could spend those same points on temp items, like the way it's done with old and new Nyzul Isle. Giving players a concrete way to see their own progress is a better way to keep them doing an event, rather then the old, outdated random drop method.
Third, I would like to see an upgrade to the /yell command, allowing players in the other cities to see any shouts for events that may interest them. This would ease up on the lag experienced in Jeuno, allowing players to set the other nations as home points again, rather then having everyone afking in the streets of jeuno.
fourth, I would like more then 3 fully merited weapon skills available. Perhaps 5? so, I guess I'm asking that the weapon skill merit category be upgraded from 15 merits total to 25 merits total
